parabolic velocity

(pa-ră-bol -ik) The velocity of an object following a parabolic trajectory around a massive body. Its velocity at a given distance from the massive body is equal to the escape velocity at that distance.

Parabolic Velocity

the velocity required for a body—for example, a space probe or an atmospheric particle—to escape from the gravitational field of an attracting body, such as the earth, the moon, or a planet, in a parabolic orbit. It decreases with the distance from the attracting body. Parabolic velocity is an example of a critical spacecraft velocity.
